TO ALL WHOM IT MAY CONCERN: p

Be it known that I, CALVIN J. HOLMN, of Chicago, in the county of Cook,and State of Illinois, have invented a new and useful Improvement inMachines for Manufacturing Heading for Coopers Ware; and I do herebydeclare and 'make known that the following is a full, clear, and exactdescription of the same, reference being had tov the accompanyingdrawings, and the `letters and figures marked thereon, which form partof this specification.

My said invention consists in arranging a saw and a planing-cylinder in-combination with a reciprocating bed or carriage, ih suche. manner thatthe material for forming heading tobarrels and similar ware may be sawedfrom the bolt or block and planed at the same time; said carriage, also,being susceptible of such an adjustment as toform onel edge of theheading thinner than the other edge, as desired.

T o enable those skilled in theart to understand howl to construct anduse my invention, I will proceed to describe the same withparticularity, making reference, in so doing, to the aforesaid drawings,in whichn Figure 1 represents a side elevation of my invention.

Figure 2 is a plan or top view of thev'same.

Figure 3 is an end view orelevation thereof, and

Figure 4 is a transverse sectional view at the line a: in iig. 2.

Similar letters of reference in the several gures denote the same partyof my invention.

A-represents a suitable frame, supporting the operating parts of themachine, B B being suitable ways or guides, upon which the reciprocatingcarriage Cmoves towards and from the saw AS and planing-cylinder G. Therequired reciprocating motion isgivento said carriage by means of 'apinion, E, operating upon the rack D, as hereinafter described. The saidcarriage has no bottom, the bolt from which the heading is cut restingupon a table, F, below, -along which it slides with the motion of thecarriage,lwhich is provided at each end lwith a row of teeth, c e, whichare clamped into the ends of the bolt, holding it securely in place, therear teeth being thrown out o r in, as desired, by means of an arm orlever, m. The said table or bed F is hinged or pivoted at one side, asshown at a, in gs. 1 and 3,'so that the opposite edge'of the bed may beraised or lowered, as desired, thus enabling the distance between oneedge of said bed and the said horizontal saw S to be made less than thedistance between the other edge of said bed and said saw, thus cuttingthe heading with one edge thinner than the other, as desired. The edgeof said adjustabledtable F, opposite the hinged side, is supported uponarms b b, which are pivoted to the stationary frame, and are attached bytheir lower ends to a rod, d, so that the adjustment of said bed F is-etfected by drawing ut or pushing in the rod de representing a catch tohold said rod from moving in and lowering the bed when the machine is inoperation. In the end of the frame of said adjustable bed F are arrangedsuitable bearings for the journals of a planing-cylinder, G, so thatsaid cylinder is always in the same plane with said bed. The saw S issuitably mounted upon a vertical shaft, H, upon which are fixed twodrums, J K, a balance-wheel, I, and a friction-gear wheel or pinion, T,as clearly shown in fig. 1,

said shaft H and its appendages being the means ofcommunicating motiontothe various parts of the machine v by means of a belt upon the drum J. Lis a belt, passing around the drumK- and the drum M, upon the shaft- N,(seen in iig. 3,) whereby, by the intervention of the drums O and I?,and a belt, P,.motion is imparted to the planing-cylinder G. 'In iig. 4is shown a vertical shaft, Q, provided with a friction or cog-wheel, R,gearing l with the aforesaid pinion T upon the shaft H, and alsolwiththe two drums U V, which are connected by belts respectively with thedrums W and X, which of themselves revolve loosely upon the shaft Y,shownfin iig. 1,

the band around U and W being crossed, so as to revolve the di'um W inthe opposite direction from drun1 X. Z represents a clutch, arrangedupon said shaft Y, between the drums W X, as seen in said Iig. 1, insuch a manner as to have a sliding movement up and downY on said shaftY, but which revolves theshaft when revolved itself, as hereinafterspecified. The said clutch is so constructed as to engage with either ofsaid drums W X, according as it may be moved up or down, by means of thelever Z or otherwise; and thus, Jwhen the clutch is in gear with thedrum X, the shaft Y is revolved in the proper direction to produce `theforward or feed-motion to the carriageC, and when said clutch is engagedwith the drum W, the retrograde motion of the carriage is produced, therelative size and lproportions of the several drums, U W and V X, beingsuch as to move the carriage C with the required speed in eachdirection. Thus it will be seen that by revolving the shaft H, m'otionis imparted to all the operating parts of the machine-'the saw S,planing-cylinder G, and carriage C-or said motion may be imparted by anyother suitable system of gearing.

It will be observed that as the carriage is moved towards and underneaththe saw, the under side of theA bolt or block, resting upon the bed F,passes over the planing-cylinder, :md is planed oil' smooth, while thes'uw is cutting the heading of the required thickness from the bolt; andwhen said piece has been separuted, the bolt is dropped down upon thebed, the carriage run buck, and the operation is repeated, bothoperations, sawing the bolt and planing the finished piece, beingaccomplished at the same time, and with one movement of' the carriage.Having described the construction :md operation of my invention, IWillspccify what I claim, and desire to secure by Letters Patent.

1. I claim the combination of the adjustable bed F, planing-cylinder Gr,und sa'w S, constructed and arranged to operate substantially as and forthe purposes specified.

` 2. I claim the combination of the bed F, planing-cylinder G, carriageC, and saw S, constructed dnd anruuged to operate in the manner and forthe purposes set'forth.
